MULTIPLE WRENCH.

Specification of Letters Patent.

Patented June c, 1916.

Application filed June 12, 1915. Serial No. 33,"70L' To all whom t may concern:

Be it known that I, Lonsnn KALINA, a citizen of the United States, and a resident of the city of New York,.borough of Brooklyn, in the county of Kings and State of -New York, have invented a new and Improved Multiple vWrench, of which the following is a full, clear, and exact descrip tion.

The object of the invention is to provide anew and improved multiple wrench arranged to provide a number of differently sized wrench heads, any one of which can be readily brought into position for engagement with a nut or similar article whether the same is visible or not, and to allow of folding the wrench into a comparatively small bundle when not in use thus rendering it exceedingly serviceable for the use of mechanics, drivers of automobiles and other persons. 0

In order to accomplish the desired result, use is made of a series of telescoping tubes lpolygonal in cross section, any one of which is adapted to be engaged with a nut or other article to be turned. Use is also made of a handle having a head iitting the innermost tube to allow of turning the wrench, the

handle being also adapted to be inserted in registering apertures Vin the tubes to allow of turning the wrench.

' A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a sectional side elevation of the wrench as applied for turning an outside nut; Fig. 2 is a similar view of the same as applied forv turning a nut in a recess; Fig. 3 is a cross section of the same on the line -3-3 of Fig. l; Fig. 4 is a sectional plan view of the same on the line l--l of Fig. l; Fig. 5 is a side elevation of the wrench showing the handle inserted crosswise in the tubes; and Fig. 6 is a sectional side elevation of thewrench with the parts in elevation and with the parts in folded position.

The multiple wrench in itsA general construction consists o a number of telescoping tubes A, B, C and D, polygonal in cross section, preferably hexagonal, for engaging r correspondingly shaped nuts E whether the latter are outside'nuts as shown inl Fig. 1, I

or nuts in a recess E as shown in Fig. 2. The tubes A, B, C and D are of the same length and one end islargerin diameter than the other end to provide a number of 4wrench heads double the number of tubes,

it being understood that the difference in the size of the ends of each tube is approximately one thirty-second of an inch, and the tubes B, C and D have their walls one- .sixteenth of an inch in thickness while the outermost tube A is thicker to withstand a heavy strain, especially as the ends of this tube are used singly as wrench heads while any one of the other tubes B, C and D is reinforced by its adjacent tube, as will be readily seen by reference to Figs. l and 2.

Each of the tubes A, B, C and D is provided with three pairs of apertures F, F and F 2, the apertures of each pair being located diametrically opposite. each other, and any one pair of apertures of one tube is adapted to register with any one pair of apertures in any one of the other tubes. Through a set of registering apertures is adapted to be passed a pin G to hold the tubes in adjusted position and this pin G is provided at one' end with a head G and a lengthwise split G2 while the other end is provided with a screw thread G3 and a central bore G4t extending inward from this end to within a short distance of the head G (seeV Fig. 6).` By providing the pin G with the split G2 resilient members are provided disengagement while using the Wrench for turning the nut E or other article.

In order to permit of conveniently turn* ing the wrench, use is made of a/handle H in the form lof a rod terminating at one end in al polygonal head H iitting into the small end of the innermost tube D, as plainly indicated in the drawings.v The other end of the handle H is .provided with an aperture H2 into which lits removably a cross bar I adapted to betaken hold or by the operator for turning the handle H with a viewto turn the tubes by the head H fitting into the innermost tube D. The head end of the handle H is provided with a bore H3 adapted to receive a portionof the cross serted crosswise through bar I when-the latter is disconnected from the aperture H2, and the other portion of this cross bar I is adapted to it into the as plainly indicated in Fig. 6. The outer end of the bore H3 is enlarged and provided with screw threads H71 into which screws the threaded. end G3 of the pin Gv'to securely hold the cross bar I folded in the handle H. The split head G' ofthe pin G fitssnugly into the 'small end of the innermost tube D to hold the handle in place ywhen folded in the innermost tube, as indicated in Fig. 6.

The several tubes are adapted to be locked in adjusted or folded position by the use of a clamping screw J having a ring-shaped handle J and screwing with itsinner end in a threaded hole K formed in the innermost tube D. rl`he shank of the clamping screw J extends-through registering slots L formed lengthwise in the tubesA, B, C

In practice, the inner terminal of th'e clamping screw J is preferably formed with a small head adapted to engage a countersink in the wallof the threaded aperture K of the inner tube D so as to hold the clampf ing screw .againstaccidental detachment andto allow the head H to pass the said inner end ofthe screw when the latter is in completely retracted position. rIhe outer endof thehandle H is preferably provided with a point H5 to permit of conveniently inserting the handle in any one of the said registering apertures F, F', F?.

From the foregoing, it will be seen that by the arrangement described the handle H can be used lengthwise, that is, axially relatively to the tubes, or the handle may be inany one set of registering apertures instead ofthe pin G, as indicated in Fig. 5. A i

In using the wrench, it is only necessary to place one end of the tubes onto thenut and to press the outermosttube downward so that the tubes which are smaller than the.

nut slide upward while the tube fitting the nut engages the latter to allow of turning the nut on turning the tubes, as above described. l

It is understood that in some v.positions of a nut E to be turned, the latter cannot be.

conveniently reached by the wrench with the handle extending crosswise, as shown in Fig. 5, and hence the handle is inserted lengthwise in the innermost tube and the several tubes are held in position by the pin G When, however, the nut can be conveniently y reached, the handlecan be inserted crosswise through the registering apertures, as shown in Fig. 5. In some cases the handle H is applied tothe pin G to form an extension for the same for turning the wrench (see dotted lines, Fig. 4.) 'Ihe cross bar I is pointed at both'ends so that -when in posican be conveniently tion and `having a tion in the pin G it serves for readily adjusting the tubes prior to finally engaging the pin G wit-h the tubes, after which the cross bar I is removed from the pin G and used as a cross bar in the handle H.

When the wrench is not in use, its parts folded, as shown in Fig. 6, so that the wrench forms a comparatively small bundle for convenient storing in a tool kit,4 or other place. I'

It'will be noticed that the user can readily engage a nut during the night or while it is dark and without much pecially if such nut is physical effort, eslocated in a dark place not easily accessible.
